Try changing your tracker\_store’s details to this: ``` tracker_store: type: mongod url: mongodb://localhost:27017 db: your_database_name username: your_username password: your_password ``` ---

Interesting. I use the details what I gave you and it works fine for me. Did you add the database name? I may be shooting blind here but is your mongod running? Under Windows you can check it in the task manager (you can open it by pressing alt+ctrl+del and selecting Task Manager from the list) under the Services tab. Check if MongoDB’s status is Running. If not, you need to restart it by right-clicking on it and selecting Restart from the popup menu. ---

Looks like you’re trying to use docker-compose file. Do you mind copying your file and pasting for more details? Just make sure you put the `depends_on` parameter in the docker-compose.yml for the container you want mongo container to be accessible from. And then retrain your bot. ---

Hi @Asmacats. Try changing your url in tracker\_store definition to `mongodb://mongo:27017` and running the instance. ---
